Can not run the Sugar Development Environment about sugar HOT 2 CLOSED

Thanks, interesting.

Your .sugar/default/logs/shell.log contains this;

/usr/lib/python2.7/dist-packages/jarabe/view/viewhelp.py:27: PyGIWarning: WebKit2 was imported
without specifying a version first. Use gi.require_version('WebKit2', '4.0') before import to ensure
that the right version gets loaded.
  from gi.repository import WebKit2

While this isn't the cause of your problem, it does show me you are using a very old version of Sugar, and we did fix several related problems after that version and before 0.112, and have fixed several since 0.112. (The file viewhelp.py does not have an import of WebKit2, from 0.111 onwards).

Could you please try again with 0.112?

Your logs also contained;

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Telepathy.AccountManager was not provided by any .service files

This looks like Telepathy is not properly installed. Please make sure you have installed all dependencies, especially telepathy-mission-control-5, telepathy-salut, and telepathy-gabble.

AVLinux probably hasn't updated to the latest Debian packages, in which the latest version of Sugar is packaged, along with updated dependencies.

Installing those dependencies and updating to the Ubuntu 18.04 (bionic) version did the trick - thank you!
